紫金山高硫浅成低温热液型铜金矿床以一套独具特色的由地开石、明矾石组成的高级泥质蚀变和由硫砷铜矿、蓝辉铜矿、铜蓝组成的铜矿物组合为特征。

Of total copper in the ore, and the main copper sulfide mineral are chalcocite and covellite.

查明了矿石中铜的赋存状态及主要的脉石成分。

The needed potential for the oxidative dissolving of chalcocite increases gradually with the decrease of Cu/S ratio in this mineral during leaching of chalcocite. When chalcocite changes fully into covellite the needed potential for leaching to produce element sulfur and Cu〓 maintains unchangeable.
